Hey!

if you remember your login credentials like application number, password, date of birth or anything else, then just login to the official website and go to application subpage. where you can download your application form by entering your application number.

or else, you might have got a copy or link to application through sms (in registered number) or even mail (registered one)

so try checking them.if it didnt work, then comment here. i could help you possibly
